Highly aligned Ti 3 C 2 T x MXene films with high anisotropic thermal conductivity

Year: 2026

Type: article

Abstract: . Temperature-dependent characterization shows that out-of-plane thermal conductivity exhibits a positive temperature coefficient up to 353 K before stabilizing into a saturation plateau near 373 K, confirming that cross-plane heat transport is fundamentally regulated by the dense interlayer physical boundaries. At the microscopic interface, surface hydroxyl groups and interfacial hydrogen-bonding networks may modify local inter-flake phonon transport channels. The in-plane thermal conductivity decreases overall with increasing temperature, reducing the anisotropy while preserving substantial directional contrast. This work provides a versatile and high-performance platform for implementing structurally oriented MXene assemblies in advanced directional thermal management.
